Improvement in crozing staves



UNITED STATES PATENT ()rrrcn JOHN PENNIE, JR, OF ALBANY, NEW YORK.

IMPROVEMENT IN CROZING STAV ES.

Specification forming part of Letters Patent No. 168,410, dated October5, 1875; application filed March 2, 1875.

companying drawings, forming a part of this specification, in whichFigure 1 represents a perspective view of a stave of a barrel,illustrating the improvements in this invention. Fig. 2 is a sectionalview of the stave, showing the head in place in the croze.

My invention relates to that part of the barrel known to the trade asthe croze-channel, which is to hold the head in place in the barrel; andconsists ina croze-channel made with two or more series of grooves, inwhich the succeeding groove or grooves will each be wider than the firstor preceding groove, so that the width of the said channel at its mouthor at the inner surface of staves may be wider than its bottom, and itssides may be made inclined with one or more steps, channels, or grooves,to present a corner or edge to engage with the usual beveled edge of thehead when inserted, and forced in the channel by the hoops binding thestaves of the barrel against the edges of the head entering the saidchanne The object of this invention is to give to the croze-channel agreater width at its mouth, so as to be capable of receiving a thickeredge of the head, and also to present to the said edge on each of itsbevels two or more corners, all of which may coact with the bevels ofthe said edge to render the joint tighter and stronger than heretoforemade.

To enable others skilled in the art to make and use my invention, I willproceed to describe it in reference to the drawings and letters ofreference marked thereon, the same letters indicating like or similarparts.

In the drawings, A represents a stave of a barrel, and one of theseveral usually employed to form the body of the barrel, each of whichis madein theusual form, and jointed together in the usual manner. B isthe croze-channel, cut the same in the ends of the several stares backof the usual howel-track b. The said croze-ohannel consists'of two ormore grooves or channels, a 0, or a, c, and e, as shown, so as to form adouble or triple channel, in which the channel a nextto the howel willbe wider than the one next succeeding channel 0, and the channel 0 will,if more than two are employed, be wider than the next succeeding channel6, as shown in the several figures, that the mouth of the channel may bemade con-v siderably wider than bottom when finished, and consist in astep form of channel formed by double or triple grooves, capable ofpresenting to the edge h of the head H several corners, each of whichwill be capable of indentin g into the wood of the edge of the saidhead, and be in their turn somewhat compressed by the head, so as toform a tight joint when forced together by the hoops.

It is to be understood that I do not confine myself to any particularnumber, more than two, of grooves or channels made successi ely to formthe said improved croze-channel,

The advantages intended to be secured by this improvement in theinvention are these: The bevel of the head may be made more obtuse, soas to leave more material at the edge of the head for the strengtheningof the same against any pressure that may be exerted from either side.The several steps of the side or sides of the channel or groove permitthe workman, who only works by the eye and not by rule or gage, to makea tighter joint of the head with the stave when the barrel is completed.

The said groove may be made deeperin the staves, so as to receive theedge to a greater depth by reason of the wider mouth of the said groove,and operates at the same time with a thicker edge for increasing thestrength of thejoint.

- Having described my invention, what I claim, and desire to secure byLetters Patent, is-

In a barrel, the croze-channel B, having two or more steps, channels, orgrooves, a 0, or a, 0, and 6, cut in each of its sides, substantially asandfor the purpose set forth.
